try Almit Sn62 HM1 RMA V14L ....its the best no clean lead paste for wetting...I sell it and it has solved wetting problems many times when users have used other pastes

Does anyone have any insight on alternatives to Indium NC-SMQ 92J solder paste for minimizing poor wetting on parts with oxidized leads (see datasheet here: http://www.dtsprocess.com/contents/articlefiles/6-SMQ92j.pdf). I am considering setting up a

Mid-chip solder balling is a defect typically associated with solder paste exhibiting poor hot slump and/or insufficient wetting during the reflow soldering process, resulting in paste flowing under the component or onto the solder resist. Once molten, this solder is compressed and forced to the side of the component, causing mid-chip solder balling.This paper documents the experimental work performed to further understand the impact on mid-chip solder balling from both the manufacturing process and the flux chemistry.

. Many of us would agree that we are still facing challenges on one of the common defects – poor barrel fill. The problem is confounded with currently High density/Multilayer thick PCB and applying Lead-free soldering
